Each message is completely customizable, but the
defaults are usually sufficient for the needs of most of our customers. Here is
how the Invitation Message appears to an invitee. Notice the default
hyperlinks:

The first link (“Demo” in this case) is simply a
link to the site itself, and the name is generated from the title given during
the initial creation within Central Administration. The second link takes the
user to the actual registration page where they can enter their information:

We’ve all been guilty from time to time of not
“reading the manual” thoroughly…especially in the IT world. :) Let’s assume for
this post that the user receives the invitation and is so excited to join an
ExCM-powered extranet site that they click the first link instead of
“register.” Unless the root level site were anonymously accessible, they would
be taken to the Sign In page for the site:

Since they have not yet created an account, they
obviously cannot sign in. Also, because we are not allowing Anonymous
Registration for this site, there is no link directly to the registration page
available. Frustration sets in, and the user never follows through with their
dream of becoming a registered user of an ExCM site.

Of course, this all could have been avoided if
the invitee had just “read the manual” (or email in this case). So how can we
prevent further dreams from being crushed in the future? By creating a custom
template for the Invitation Mail Message that removes the hyperlink.

The first thing we need to do is create a new
Mail Definitions list and item containing the customized template. To do this,
we need to navigate to Site Actions – More Options:

From there, we select “Mail Definitions” and give
the new list a name:

After clicking “Create,” we are taken to the new
list. Now we to select “New Item” from the menu:

Now we need to give our new template a name, mail
subject, and mail body. The first two are self-explanatory, but the mail body
itself needs to be in HTML format. Here is a sample of the existing Invitation
Mail Message found on our help site:

I am going to copy and paste that section into
Notepad so we can take a closer look at the edits we need to make. In this
scenario, I am looking for the following value:

I am just going to replace the entire reference
with regular text so that it will now read:

“…the best ExCM-powered Extranet site on the
planet!”

After that, I copy and paste our text from the
Notepad file into the mail body area for the template:

After clicking “Save,” we can now see that our
new template has been successfully created:

Now, let’s use this new template for our ExCM
invitations. We'll navigate to Site Actions – Site Settings and select “Mail
Settings” from the ExCM management menu. From there, we'll select the
“Invitation” message under “Mail Messages:”

In the middle of the pop-up window, we need to
select “Use Custom Template” and select the one we just created and click
“Save:”

We can now see that the Invitation Mail Message
is using our custom template:

Now, let’s test it out. After inviting another
user and opening the email, we now see this:

Our custom template is now working and we have
prevented future invitees from despair!

Of course, you can get MUCH more detailed in the
customization of your messages. You can use HTML to change the colors and
fonts, include graphics, etc. Regardless of complexity, however, the process
remains the same.
